CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of U.S. Provisional Application No. 63/067,940, filed on Aug. 20, 2020. The entire disclosure of the application referenced above is incorporated herein by reference.

FIELD

The present disclosure relates to vehicles and more particularly to systems and methods for measuring and managing odor brought into rental vehicles.

BACKGROUND

This section provides background information related to the present disclosure which is not necessarily prior art.

Vehicles have been recalled due to carbon monoxide entering their passenger cabins and for other reasons. Humans may be overcome by carbon monoxide and lose consciousness.

There may be numerous other situations where chemicals could be present within a passenger cabin of a vehicle. For example, a user may bring an aerosol can in to the passenger cabin of a vehicle and forget to take it out. Due to heat or cold, the aerosol can could emit its contents into the passenger cabin. One or more users could enter the vehicle later and breathe the contents without knowledge.

Electric vehicles include one or more batteries that contain chemicals, such as lithium. The batteries may be located under the passenger cabin and, under some circumstances, can rupture and emit chemicals. Some chemicals that may be present within a passenger cabin of a vehicle may be odorless and colorless.

DETAILED DESCRIPTION

Example embodiments will now be described more fully with reference to the accompanying drawings.

Odors tend to build up in vehicles over time. In personal vehicles, frequent users (e.g., the owner(s)) of the vehicle may not perceive the odor within the passenger cabins of their vehicles due to their frequent use of the vehicles. Non-frequent users of a vehicle, however, may perceive and be bothered by the odor within the passenger cabin of the vehicle. For example, renters of rental vehicles may perceive and be bothered by the odor within the passenger cabins of rental vehicles. Odor within the passenger cabin of a rental vehicle may decrease a value of the rental vehicle to an owner/operator of the rental vehicle. Rental vehicles may also be referred to as fleet vehicles and may refer to single owner vehicles that are used by multiple different people. Rental vehicles may include corporate fleet vehicles, shared vehicles, taxies, busses, etc.

The present application involves monitoring changes in odor within the passenger cabin of a rental vehicle. For example, a change in odor during a rental of a rental vehicle may be determined based on an odor before the rental and an odor after the rental. If the odor introduced during the rental meets one or more predetermined criteria (e.g., a magnitude of the odor is greater than a predetermined value), the renter may be charged for remediation of the odor. As another example, introduction of an odor (e.g., of food, an animal, etc.) may be detected during a rental. The renter may be charged for introducing the odor into the vehicle (e.g., per a rental contract for the rental vehicle) and/or a targeted advertisement associated with the odor may be output to the renter of the vehicle. Advertisers may pay the owner/operator of rental vehicles for providing targeted advertisements regarding advertised goods and/or services. Fees paid for the targeted advertisement may help offset fees associated with odor remediation.

FIG. 1 includes a functional block diagram including an example vehicle 5. The vehicle 5 includes a control module 8 and one or more olfaction sensors, such as olfaction sensor 10. Examples of olfaction sensors in vehicles include, for example, particulate matter sensors, carbon monoxide (or other carbon oxide) sensors, volatile organic compound (VOC) sensors, and other types of sensors. The vehicle 5 may include one or more different types of olfaction sensors.

The olfaction sensor(s) are each configured to measure an amount of one or more chemicals within a passenger cabin of the vehicle 5. For example, the vehicle 5 may include a particulate matter sensor configured to measure one or more amounts (e.g., concentrations or mass flow rates) of particulate of one or more different sizes in air within the passenger cabin. Additionally or alternatively, the vehicle 5 may include a carbon monoxide sensor configured to measure an amount (e.g., concentration) of carbon monoxide in air within the passenger cabin. Additionally or alternatively, the vehicle 5 may include a VOC sensor configured to measure an amount (e.g., concentration) of VOCs within the passenger cabin.

The control module 8 may receive the measurements from the olfaction sensor(s) and take one or more remedial actions based on the measurements. For example, when one or more amount of one or more chemicals (e.g., particulate, carbon monoxide, VOCs) measured by one or more olfaction sensors is/are greater than one or more respective predetermined amount/s (e.g., of particulate matter, carbon monoxide, or VOCs, respectively), the control module 8 may take one or more remedial actions. The predetermined amount/s is/are greater than zero.

For example, the control module 8 may open one or more windows 12 of the vehicle 5 when the amount of a chemical is greater than the predetermined amount. Additionally or alternatively, the control module 8 may generate an alert within the vehicle 5 when the amount of a chemical is greater than the predetermined amount. For example, the control module 8 may generate or display a visual alert, such as via a visual indicator 14 that is visible within the passenger cabin of the vehicle 5. The visual indicator 14 may be, for example, one or more indicator lights, a display, or another suitable type of visual indicator. Additionally or alternatively, the control module 8 may output an audible alert, such as via one or more speakers. Additionally or alternatively, the control module 8 may output a tactile alert, such as via turning on one or more vibrating devices, such as located in one or more seats, in a steering wheel, or in another suitable location.

Additionally or alternatively, the control module 8 may turn on a heating ventilation and air conditioning (HVAC) system 16 of the vehicle 5 when the amount of a chemical is greater than the predetermined amount. The control module 8 may, for example, turn on a blower of the HVAC system 16 and control one or more actuators of the HVAC system 16 to circulate or recirculate air from within the passenger cabin to outside of the passenger cabin.

Additionally or alternatively, the control module 8 may store an indicator in memory of the vehicle when the amount of a chemical is greater than the predetermined amount. The indicator may indicate that the amount of the chemical was greater than the predetermined amount. The control module 8 may also store a time stamp (e.g., including a date and a time of the occurrence) with the indicator.

Additionally or alternatively, the control module 8 may transmit an indicator to a remote device 20, such as of a fleet operator, when the amount of a chemical is greater than the predetermined amount. The control module 8 may transmit the indicator via one or more communication networks, such as a cellular communication network, a satellite communication network, a Wi-Fi communication network, or another suitable type of communication network.

The olfaction sensor 10 may be implemented within the HVAC system 16 (e.g., within a duct) or in another location within the passenger cabin of the vehicle 5.

As discussed above, the vehicle 5 may include multiple olfaction sensors. For example, the vehicle 5 may include a VOC sensor and a particulate matter sensor.

The vehicle 5 may be a rental vehicle. Each vehicle may have a baseline odor or smell within its passenger cabin. When the vehicle 5 is rented (in the example of a rental vehicle), the renter may introduce one or more scents/odors to the vehicle. The odor of rental vehicles may therefore change over time and may become unpleasant to later renters/users of that rental vehicle. This may decrease a value of the vehicle to an owner/operator of the vehicle 5, cause the owner/operator to incur expense to minimize odor, etc.

The present application involves determining one or more odors introduced to the passenger cabin of the vehicle 5 by a renter while the vehicle 5 was rented by the renter.

FIG. 2 is a functional block diagram of an odor system. The vehicle includes olfaction sensors 100. For example, the olfaction sensors 100 may include a VOC sensor and a particulate matter sensor.

A triggering module 104 selectively triggers the VOC sensor and the particulate matter sensor to take measurements. For example, the triggering module 104 triggers the VOC sensor and the particulate matter sensor to determine one or more amounts of one or more VOCs within the vehicle 5 and one or more amounts of one or more particulates within the vehicle 5 prior to the renter beginning to use the vehicle 5 (before rental).

An odor determination module 108 determines a baseline odor within the passenger cabin of the vehicle 5 based on the measurements from the VOC and particulate matter sensors before the renter begins to use the vehicle 5. The odor determination module 108 determines the baseline odor using an odor database 112. The odor database 112 may include mapping of amounts of VOCs and particulate matter to odors.

The triggering module 104 also triggers the VOC sensor and the particulate matter sensor to determine one or more amounts of one or more VOCs within the vehicle 5 and one or more amounts of one or more particulates within the vehicle 5 after the renter has returned the vehicle 5 (after rental). The odor determination module 108 determines a post rental odor within the passenger cabin based on the measurements from the VOC and particulate matter sensors after the renter returns the vehicle 5.

The triggering module 104 may also selectively trigger the VOC sensor and the particulate matter sensor to determine one or more amounts of one or more VOCs within the vehicle 5 and one or more amounts of one or more particulates within the vehicle 5 during the rental. The triggering module 104 may trigger the VOC and particulate matter sensors, for example, each predetermined period (e.g., once per day, every X hours where X is an number greater than zero, every Y minutes while the vehicle is ON where Y is an integer greater than zero, etc.) during the rental.

The odor determination module 108 determines during rental odors within the passenger cabin based on the measurements from the VOC and particulate matter sensors during the rental.

A charge module 116 determines whether to charge the renter for the odor (e.g., remediation of the odor) introduced to the passenger cabin by the renter based on the baseline odor and the post rental odor. For example, the charge module 116 may apply a charge to an account (e.g., a payment card) of the renter when a difference between the baseline odor and the post rental odor is greater than a predetermined amount.

Additionally or alternatively, the charge module 116 may apply a charge to the account of the renter when the post rental odor or a during rental odor includes one or more unnatural odors (e.g., relative to the baseline odor). For example, some food smells may be considered natural odors (e.g., produce), while smoking (e.g., tobacco, marijuana, etc.), excessive body odor, and chemical agents may be considered unnatural odors. The present application is also applicable to other examples of natural and unnatural odors.

The odor database 112 may include a list of odors that are natural odors and a list of odors that are unnatural odors. By charging the renter for excessive body odor, the renter may be charged if sufficiently proper hygiene is not practiced during the rental. By charging the renter for smoking, the renter may be charged if smoking occurs within the vehicle during the rental.

Additionally or alternatively, the charging module 116 may apply a charge to the account of the renter when the post rental odor or a during rental odor (e.g., relative to the baseline odor) includes one or more predetermined odors stored in the odor database 112. The predetermined odors may be associated with events that the owner/operator of the vehicle 5 does not want to occur (and may have contracted with renters to not occur) within its rental vehicles. Each renter may be contractually obligated (in a rental contract signed before rental) to not perform any of the events (associated with the predetermined odors) within the vehicle 5 during rental. Examples of the predetermined odors and events include odors associated with sexual intercourse, drug use, excessive body odor, excessive food smell, spilled food/drink, mold, mildew, rotting organic material, etc.

The post rental odor may be used as a baseline odor for a next renter or another baseline odor may be determined before the next renter begins to use the vehicle 5. In various implementations, the baseline odor may be predetermined and stored. The baseline odor may be set, for example, based on the smell of a new vehicle or the smell of the rental facility in which the vehicle 5 is stored while not rented.

In various implementations, an advertisement module 120 may selectively transmit targeted advertisements to the renter (e.g., a mobile device associated with the renter) or the vehicle 5 during the rental. The advertisement module 120 may transmit a targeted advertisement to the renter of the vehicle 5, for example, based on a during rental odor (i.e., an odor determined during rental by a renter).

For example, when a during rental odor indicates that the renter brought a specific type of food (e.g., Mexican food) into the vehicle 5, the advertisement module 120 may transmit a targeted advertisement associated with Mexican food (e.g., a coupon or offer from a Mexican restaurant, such as Taco Bell) to the renter or the vehicle 5.

As another example, when a during rental odor indicates the occurrence of an event within the vehicle 5, the advertisement module 120 may output and/or transmit a targeted advertisement associated with one or more goods and/or one or more services associated with the event. The goods and/or services associated with events may be stored in an advertisement database. Examples of events include eating, smoking, presence of one or more pets, and other types of events.

The advertisement module 120 may output targeted advertisements within the passenger cabin. For example, the advertisement module 120 may visually display a targeted advertisement on one or more displays 50 within the passenger cabin and/or audibly output a targeted advertisement via one or more speakers 54 within the passenger cabin. Additionally or alternatively, the advertisement module 120 may transmit a message (e.g., an email, a text message, a short message service (SMS) message, etc.) including a targeted advertisement to an account or phone number associated with the renter of the vehicle.

The targeted advertisement advertises products and/or services associated with the event. For example, if eating is detected, the advertisement module 120 may output a targeted advertisement regarding a restaurant and/or provide a coupon regarding a restaurant. If smoking is detected, the advertisement module 120 may output a targeted advertisement regarding a business that aims to help humans stop smoking. If an animal is detected, the advertisement module 120 may output a targeted advertisement regarding a pet store and/or provide a coupon regarding a pet store.

The odor database may include a lookup table of combinations of particulate measurements and VOC measurements that correspond to different odors. As an example, using the odor database 112, the odor determination module 108 may determine that eating is occurring when the amounts of particulate and VOCs provide a first combination of particulate and VOC measurements indicative of food within the vehicle. Using the odor database 112, the odor determination module 108 may determine that smoking is occurring when the amounts of particulate matter and VOCs are a second combination of particulate and VOC measurements indicative of smoking. Using the odor database 112, the odor determination module 108 may determine that an animal is present within the vehicle when the amounts of particulate matter and VOCs are a third combination of particulate and VOC measurements indicative of an animal. An example lookup table/database including some examples is provided below. The present application is also applicable to other odors and events.

Measurement combination Odor PM1 and VOC1 Food/eating PM2 and VOC2 Smoking PM3 and VOC3 Animal(s) . . . . . .

FIG. 3 includes an example radius graph (at 0-63 sensor nodes in this example) of VOCs and particulate matter measured at a seat (a rear seat in this example) within the passenger cabin at corresponding sensor nodes. Trace 304 tracks the amount of VOCs and particulate at the seat before a vehicle condition occurs or odor is introduced (e.g., baseline). Trace 308 tracks the amount of VOCs and particulate at the seat over time and compares the measurement to baseline trace 304.

As illustrated, the measurements between the baseline (before the vehicle condition occurs) 304 and the measurements after an event has occurred 308 allow the odor determination module 108 to identify the introduction of odors and to identify excessive odor introduction into the vehicle during a rental. In various implementations, the odor determination module 108 may diagnose odors/events (e.g., pets, food, type of food, etc.) within the passenger cabin similarly. In the example of food, measurements between the baseline (before the odor is introduced) and the measurements after the odor is introduced may allow the odor determination module 108 to distinguish between types of odors within the passenger cabin and between types of events in the passenger cabin.

FIG. 4 includes an example table including conditions that may be associated with different types of events and odors within the passenger cabin. While example events and odors are provided, the present application is also applicable to other events and odors.

FIG. 5 is a functional block diagram of an example implementation of a control system. As discussed above, the olfaction sensor 100 may include VOC sensor and a particulate matter sensor.

The odor determination module 108 may store and retrieve the baseline odor from memory 508. One or more remedial actions may be taken in addition to the above in response to an odor determined by the odor determination module 108, such as a during rental odor or an after rental odor.

For example, a window actuator module 516 controls actuation (opening and closing) of one or more window actuators, such as window actuator 520, of the vehicle. The window actuator 520 opens (e.g., lowers) and closes (e.g., raises) a window of the vehicle. The window actuator module 516 may control one or more window actuators to open one, more than one, or all of the windows of the vehicle when a predetermined odor or odor change is detected. Opening the window(s) may include, for example, opening the window(s) to a partially open position further than the window(s) is/are presently open or opening the window(s) to a fully open position.

Additionally or alternatively, an alert module 524 may generate an alert (e.g., visually the visual indicator 14, audibly via one or more speakers, and/or haptically via one or more vibrating devices) when a predetermined odor or odor change is detected. Additionally or alternatively, a blower control module 528 may turn on a blower 532 of the HVAC system when a predetermined odor or odor change is detected.

Additionally or alternatively, a communication module 540 may wirelessly transmit an indicator to the remote device 20 via one or more antennas 544 when a predetermined odor or odor change is detected. Additionally or alternatively, a storage module 548 may store an indicator in the memory 508 when a predetermined odor or odor change is detected. The indicator may indicate that the predetermined odor or odor change that occurred. The storage module 548 may also store a time stamp (e.g., including a date and a time of the occurrence) with the indicator. A clock may track the date and time.

As discussed above, the charge module 116 may charge an account (e.g., a credit card account) associated with the renter in response to a predetermined odor or odor change occurring. The charge module 116 may transmit an instruction to charge the account of the renter to the remote device 20 via the communication module 540, and the remote device 20 may initiate the charge to the account of the renter. The advertisement module 120 may output a targeted advertisement via one or more output devices 552 (e.g., speakers or displays) when a predetermined odor or event is detected.

FIG. 6 is a flowchart depicting an example method of detecting odor within vehicles and taking one or more actions based on detected odors. Control may begin with 604 where the odor determination module 108 may obtain a baseline odor of the vehicle from the memory 508. In various implementations, 604 may be omitted.

At 608, the odor determination module 108 determines the present odor within the vehicle based on the amounts of VOCs and particulate measured using the VOC and particulate sensors and the odor database 112. At 612, one or more modules of the control module 8 may determine whether a predetermined odor is present within the vehicle. If 612 is true, control may continue with 616. If 612 is false, control may end. At 616, one or more actions may be taken based on the detection of the predetermined odor. For example, the storage module 548 may store an indicator of the predetermined odor in the memory 508, the charge module 116 may charge the account of the renter of the vehicle, the advertisement module 120 may output a targeted advertisement, the blower control module 528 may turn on the blower 532, the window actuator module 516 may open one or more of the windows 12, and/or the alert module 524 may output an alert. While FIG. 6 is shown as ending, control may return to 604.

FIG. 7 is a flowchart depicting an example method of detecting odor within vehicles and taking one or more actions based on detected odors. Control may begin with 704 where the odor determination module 108 obtains the baseline odor of the vehicle before a renter begins renting the vehicle. The baseline odor may be stored in the memory 708, such as from after a last rental.

At 708, the charge module 116 determines whether the rental of the vehicle has ended. For example, the charge module 116 may determine whether the vehicle has been returned to a location of an owner of the vehicle or a predetermined period has passed since the rental began. The predetermined period may be a term of the rental contract. If 708 is true, control may continue with 712. If 708 is false, control may remain at 708.

At 712, the odor determination module 108 may determine the odor within the vehicle (after/post-rental odor) based on the amounts of VOCs and particulate measured using the VOC and particulate sensors. At 716, the charge module 116 may determine a change (e.g., difference) in odor between the baseline and post-rental odors. The change may include, for example, a change in VOCs and a change in particulate.

At 720, the charge module 116 determines whether to charge the renter for odor introduced to the vehicle during the rental based on the change. The charge module 116 may determine to charge the renter, for example, one or more of the changes is greater than a predetermined value. If 720 is true, the charge module 116 charges an account of the renter of the vehicle for odor introduced to the vehicle at 724, and control may end. If 720 is false, the charge module 116 may not charge the account of the renter, and control may end.

As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items.

Although the terms first, second, third, etc. may be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not be limited by these terms. These terms may be only used to distinguish one element, component, region, layer or section from another region, layer or section. Terms such as “first,” “second,” and other numerical terms when used herein do not imply a sequence or order unless clearly indicated by the context. Thus, a first element, component, region, layer or section discussed below could be termed a second element, component, region, layer or section without departing from the teachings of the example embodiments.

Spatially relative terms, such as “inner,” “outer,” “beneath,” “below,” “lower,” “above,” “upper,” and the like, may be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. Spatially relative terms may be intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as “below” or “beneath” other elements or features would then be oriented “above” the other elements or features. Thus, the example term “below” can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
